Definitions
- the present invention relates to method and/or apparatus for assuring the authenticity of drugs or other substances packaged in glass or plastic containers, particularly syringes.
- each of the glass-packaged products should be individually identifiable, such that the correct items are known to be in the correct box at specified stages in the production process and in the supply chain.
- Methods of marking glass products for security purposes include printing methods and laser marking methods on the surface of the material. Usually these processes use a code for track and trace purposes.
- Ink-jet printing technology is one process for coding products for track and trace purposes. This has been applied in the pharmaceutical industry on various substrates including glass, to create numerical codes and bar codes. (ref Marking & Coding Solutions for Pharmaceutical Applications, Videojet Technologies Incorporated, https://my.videojet.com/videojet/distributors/documents/support/Brochures/v-pharma-flyer.pdf)
- a long-wave CO 2 laser with scanning optics has been used to engrave a translucent data matrix code onto the surface of glass syringe barrels.
- the code is 2 ⁇ 2 mm in size comprising a 14 ⁇ 14 data matrix. It is optically read using a camera with back-lighting, and read as a black & white code by image processing software. (ref Pharm. Ind. 71, No. 10, 1770-1774 (2009) and Pharm. Ind. 71, No. 11, 1945-1948 (2009); ECV Editio Cantor Verlag, Aulendorf, Germany).
- Data matrix codes of 1 ⁇ 1 mm size have also been laser etched onto the finger rest of the syringe.
- green lasers have been used to mark anti-fake labels below the surface of glass bottles for security purposes.

- U.S. Patent Publication No. 2010/0119808 teaches that changes to the refractive index inside glass have been achieved using radiation having a wavelength of up to 400 nm to form subsurface marks up to 50 ⁇ m in size. No microcracks are created in the glass and no surface marking occurs. The subsurface marks can be created in a range of 20 to 200 microns below the outer surface of the glass.
- This '808 publication is expressly incorporated by reference herein, in its entirety.
- Remelted glass zones can be created inside bulk glass using a pico-second laser. These zones result in a local refractive index change. (Ref Evaluation Of Non-Linear Absorbtivity In Internal Modification Of Bulk Glasses By Ultra-Short Laser Pulses, by Isamo Miyamoto, Christian Cvecek, Michael Schmidt, Optics Express, 23 May 2011/Vol. 19, No. 11, which is expressly incorporated by reference herein, in its entirety.)
- U.S. Pat. Nos. 6,573,026 and 6,853,785 teach that patterns can be created in bulk glass substrates by using a femtosecond laser to modify the refractive index.
- the pulsed laser beam is translated along a scan path to change the refractive index without resulting in any laser induced physical damage of the material.
- Each of these '026 and '785 patents is expressly incorporated by reference herein, in its entirety.
- International Patent Publication No. WO2007/033445 teaches the use of a femtosecond laser to mark codes inside the glass wall of a syringe, to track the products. This '445 publication is also incorporated by reference herein, in its entirety.
- OCT optical coherence tomography
- U.S. Pat. No. 6,469,489 describes an array sensor used for parallel optical low coherence tomography which enables real time 3D imaging for topographic and tomographic structures. It provides fast, three dimensional and structural information with spatial resolution in the micrometer range. In depth OCT can achieve resolutions between 10-100 nm for high quality surfaces.
- a plurality of electrical detection circuits with parallel outputs can form a one-dimensional or two-dimensional array sensor for the coherent or heterodyne analog detection of intensity modulated optical signals simultaneously for all pixels with a high dynamic range.
- the array sensor may be used for optical 3D measurements, and especially in optical low-coherence tomography.
- OCT is known for investigating the human skin, to control the quality of fast production processes, in SMD pick and place systems, as well as in mechanical inspection systems. Instead of using a time-modulated interferometric signal, frequency domain OCT uses a broad band light source and advanced Fourier analysis to provide very fast and accurate 3D images of objects, such as the human retina.
- the present invention uses a laser beam (eg from pico-second or femto second laser) to create features inside the product, (also referred to as the product container) below the surface, wherein the features are 3-dimensional and on the order of 0.5-50, 1-10, 1-20, 5-20, 5-30, 5-50 ⁇ m in size.
- the product may be glass or plastic.
- the features may be micro-cracks, changes in density or refractive index, or small bubbles or voids. In the context of this specification these features are called marking spots.
- Micro-crack features and bubbles can also be created inside glass using ns and ps pulses. Density changes are created by fs and ps laser pulses. Laser pulse durations are 1-10 ps, 100 fs-1 ps and 10-20 ps.
- a pulse train i.e. a well defined sequence ofpulses
- this invention can be used to create the above features at different depths (in different depth layers) in the glass.
- a 3-dimensional pattern of features in the glass can be produced, with a precision between 1-10, 1-20, 1-30, 5-20, 5-30, 5-40 and 5-50 microns. This pattern may or may not be visible to the naked eye.
- the depth step between each depth layer should be at least a quarter the average size of the microscopic laser marking feature or larger.
- optical measuring techniques such as optical coherence tomography (OCT), and in particular time-domain parallel OCT (pOCT)
- OCT optical coherence tomography
- pOCT time-domain parallel OCT
- Other OCT techniques such as frequency domain OCT, and single channel OCT can also be applied in such a way that the laser marks are read in 3 dimensions. This can then be read as a sequence of different lateral positions and depths.
- OCT is especially suited to accurately measuring features inside the glass which are due to local changes in index of refraction, i.e. small density changes. Codes made with such small density changes can be such that they are invisible to the human eye or normal 2D cameras. This is particularly true if the code does not create diffraction effects (for example because the features are too coarse i.e. larger than 3 microns and/or are not arranged sufficiently regularly to produce diffraction).
- the OCT method is also excellent for detecting and measuring 3D patterns of tiny microscracks that cause light scattering.
- Two or more distinct depth levels can be used to create a digital code. From the top surface, the pattern could be seen as a 2D barcode, or a regular pattern without apparent code although it is in fact created in 3D inside the glass and contains the code. With more than two depth levels, a more complex code is possible.
- Having a fast 3D optical measuring technique available also allows measuring the distance to the glass surface accurately within a precision of 30 microns or better. It also allows measuring the glass curvature and flatness. These can be taken into account during the laser writing step to enhance the regularity of the laser markings.
- a typical process sequence in writing and reading the 3D code on a product involves the following:
- FIG. 1 is a schematic which shows, in exemplary form, a 2D datamatrix code.
- FIG. 2 shows, in schematic form, two different possibilities for a group of laser created spots on the product container.
- FIG. 3 includes photographic reproductions which show optical microscopy and pOCT measurements of laser written marks inside the glass body of a syringe.
- FIG. 4 shows an example of 2D barcodes written below one another, at different levels, within the glass container.
- FIG. 5 is a schematic which show the use of diffractive optics to create multiple focal points from a laser beam.
- FIG. 6 includes photographic reproductions which show microcracks created in glass by using a ps laser, at different percentages of average power.
- FIG. 7 is a photographic reproduction which shows 100 ⁇ m wide square “pixels” written into glass at a depth of 200 ⁇ m, using lines made of microcracks.
- FIG. 8 is a photographic reproduction which shows microdata in glass at 200 ⁇ m in depth, made up of remelted zones, produced by a ps laser at different percentage levels of average laser power.
- FIG. 9 is a photographic reproduction which shows the lens effect caused by a curved top surface of glass, shown by images of pOCT measurement.
- FIG. 10 is a photographic reproduction which shows a blister nest, i.e. a tray, with glass syringes, as seen from the top.
- FIG. 11 is a schematic which shows a conceptual layout of a system for the internal marking of the flanges of syringes located in a nest.
- FIG. 1 shows a 2D datamatrix code.
- the black/white contrast in glass can be generated by laser writing. Small gas bubbles or melted and solidified glass zones written by short pulse lasers give an image contrast in 3D OCT tomography.
- the white and black regions can be readily distinguished by having a different kind of laser point arrangement.
- a black region could be n laser points (where n is a natural number including 0) at one level below the glass surface and the white region could be an arrangement of m laser points (where in is a natural number including 0) at a different depth below the glass surface.
- Combinations of k distinct depth levels within the same digital region i.e. black/white
- Advantageously k lies between 1-10.
- FIG. 2 shows two different possibilities for arranging a group of laser spots on 2 depth levels below the glass.
- the 4 points all denote the same black or white square in the datamatrix code.
- the number of points does not need to be four and the points need not be at the same distance or arranged in a square. Other arrangements would also be possible.
- FIG. 3 shows optical microscopy (left) and pOCT measurements (right) of laser written marks inside the glass body of a syringe.
- the optical microscopy images on the left show a chessboard pattern of marks written by the laser, but not the depth of the pattern.
- the black & white images from the pOCT show one of the squares in the pattern from above (upper right), and a cross-section (lower right) through the glass.
- the cross-section shows the top surface of the syringe as strong signal line, and the laser written marks as a lower contrast line below the surface.
- the present invention contemplates the use of two or more 2D barcodes written at different depths. For instance, one variation of the invention would be to write a 2D barcode at the surface or within the volume of the glass, at a second level below the surface. This is shown in FIG. 4 . Then above or below, (or perhaps even at the same level beside this first code) a second code is written which acts as a digital verification signature, and is encrypted.
- This encrypted second code can be a 2D bar code but is not limited to such a code.
- Other examples include a random verification pattern, a linear bar code, a digital image, a readable text, or a number block, at different levels below each other inside the glass.
- a normal 2D bar code would be readily readable for tracking information, and the second code would be a cryptographic signature readable only with a secret key. This could contain, for example, an encrypted product identity to verify that the product is genuine.
- the system would work similar to a digital signature of an e-mail or an electronic picture, where the mail content is actually readable to everyone, but the signature is genuine and verifiable by cryptographic means.
- the cryptographic code i.e. “digital signature”
- the overt barcode containing the open information is written directly above this code.
- Such an arrangement would prevent the cryptographic code from being tampered with because any laser beam used to tamper with the cryptographic code would need to pass through the overt code and would be scattered and diffracted thereby, making it exceedingly difficult to control a rewriting of the cryptographic code. If the code is in or at the edge of the flange of a syringe, it is even more geometrically difficult to write with a laser from below Therefore such a system would be extremely tamperproof.
- the present invention also contemplates the use of diffractive optics, scanner, or a beamsplitter to write at multiple points simultaneously.
- Each point can be written multiple times using a diffractive optic, so that many points close together are produced simultaneously as a 3D point cloud, as shown in FIG. 5 . Because this depends on the specific optic used, this is extremely difficult to copy. Depending on the design of the diffractive optics, multiple convergent or divergent beams can be produced, allowing identical or different focus depths to be created simultaneously.
- a similar effect can be created using a high speed scanner (active mirror) or a beam splitter optic. However, in this latter case, only a few points would be created at one time.
- the invention contemplates creating pixels inside the glass, the pixels comprising fine lines of micro cracks.
- Pixels in a datamatrix barcode or other pattern can be created using a ps laser, by writing lines made up of rows of 5 ⁇ m long microcracks, eg 50-100 ⁇ m pixels containing 10, 20 or more such lines.
- the precision level of the laser is such that it is possible to write between and below these lines at deeper levels within the glass.
- FIG. 6 shows microcracks produced in the glass at different power levels. The cracks are produced using the laser at a low repetition rate (10 KHz), and a feed rate of 20 mm/sec with a pulse energy of 20-3 ⁇ J. The size of the microcracks changes with the power level used.
- FIG. 7 shows square pixels made up of 5 ⁇ m wide lines, where each line is a row of 5 ⁇ m long microcracks.
- FIG. 8 shows microdots made up of remelted zones, produced at different percentage levels of average laser power.
- the microdot formation threshold in this example is about 2.2 W.
- Minimum size of microdot farmed here is about 40 ⁇ m.
- the curvature of a glass flange creates an immersion lens effect. More specifically, the curvature of a glass surface, such as the top surface of a syringe flange, creates a refraction effect on a laser beam.
- the thick grey-white square is part of the top surface of a syringe flange.
- the chess-board pattern seen is a pattern of laser-written marks within the glass.
- the centre top image shows a vertical view of part of the chess-board.
- the far right image is a cross-section view showing the curved top surface (thick white line) and the curved laser-written pattern in the glass below.
- This effect can be used to create points inside the glass that are closer together, due to the lens effect, and also smaller in focus.
- This effect can also be used to create a curved (non-planar) pattern or barcode where marks or patterns appear optically to overlap. This makes a pattern or barcode very difficult or impossible to read using an optical microscope, but the pattern can be read easily using a pOCT system.
- FIG. 11 shows a conceptual layout for such a system 10 , wherein a nest 12 of syringes is positioned below the axes of a frame 14 that moves relative to the tray 12 , to move each of the syringes in alignment with a writing apparatus 15 that is mounted on the frame 14 .
- the writing apparatus includes a measuring device for measuring the distance to the surface of the syringe that is aligned therewith and also the contour, i.e. the flatness, of the surface.
- the writing apparatus 15 includes a laser device 18 , further including mirrors 19 and a laser source 20 .
- a laser beam is directed via the mirrors 19 , via a scanner, toward the flange of the aligned syringe for laser marking.
- the writing apparatus 15 includes a reading device, such as a pOCT measurement head, to readily verify that the correct 3D code has been written on the aligned syringe.
- a reading device such as a pOCT measurement head
- the syringes are filled and closed while located in the same tray 12 .
- the 3D code is also identified with a master controller, to keep track of the specific substances that are associated with the predetermined 3D code.

Abstract
Description
-
- The genuine and correct contents arrive at the correct locations.
- Product containers can be traced back through the supply process stages for verification or troubleshooting.
- Product containers cannot be counterfeited, which would result in the wrong substance being delivered to a customer.
- The wrong genuine article cannot end up in the wrong location or with the wrong person.
- Customers have complete confidence that none of these above-stated problems has occurred, because there is a secure system in place.
-
- 1. Inaccuracy of depth of code, as the depth is not measured.
- 2. Low production yield because of light reflected from surfaces which sometimes makes reading of the codes with normal cameras very difficult.
- 3. In printed systems and surface engraving, which give good image contrast, there is the danger of particle contamination.
-
- 1. Measuring the 3D topology of the glass surface of the product within less than is and determining within an accuracy of 30 microns or better, the distance from an inspection system, i.e. the writing apparatus, to the surface.
- 2. Writing a predetermined 3D code below the surface of the product with a short pulsed laser system, preferably using a 1-20 ps, 20-100 ps or a ns or a 100 fs-1 ps laser, with one or several laser pulses used to make the markings.
- 3. Reading, with a 3D measuring system, the 3D code that has been written below the surface of the product, for example with OCT or pOCT or a variant thereof, thereby to verify the product.
- 4. if the code cannot be read, repeating steps 1-3 or 2-3 on the same product to minimize rejects or to mark the product as a reject.
The use of a 3D code in this manner has the following advantages over existing solutions: - it is very difficult to copy
- it is difficult to decode except by those with the required equipment and authorization.
- it is tamper-proof.
- defects on and in the glass can be more easily distinguished from the laser markings, thereby making the reading and writing step more reliable than with conventional 2D camera systems.
- the 3D code is secure from external damage.
- Because pOCT uses a time modulated optical signal as a reference, reading errors due to wrong reflexes and additional illumination is strongly reduced.
